BOTTOM-DUIVIPING AND HANDLING BUCKET.

Specification of Letters Patent.

Patented Nov. 14, 1905.

Application filed August 14, 1905. Serial No- 274,072.

To (tZZ whom, it may concern:

Be it known that I, PETER 0. Hum, J r., a citizen of the United States,residing at Washington, in the District of Columbia, have in ventedcertain new and useful Improvements in Bottom-Dumping and HandlingBuckets, of which the following is a specification.

The invention to be hereinafter described relates to concrete-handlingbuckets employed to contain, transport, and deliver heavy masses ofconcrete. In such devices it is desirable that means be provided forenabling all or only a part of the bucket contents to be delivered,according to the necessities of use, and that the bucket be soconstructed that it may rest upon a support, such as the ground or flatcar, without liability of injury to the dumping mechanism. Owing to themass and weight of concrete contained in such a bucket it is also adesideratum that the bottom-dumping meansshall be so contrived that thestrains shall be properly transmitted to the suspending means when suchbucket is raised by derrick or otherwise.

With these general considerations in view the object of the presentinvention is to provide a concrete-handling bucket with bottomdumpingdoors of simple yet eflicient construction, which shall be easilyoperated to discharge all or any portion of the bucket contents, asdesired, and in which means shall be provided for enabling the bucket torest upon a support or be suspended from a derrick or other means, theweight at such times being distributed through the bottom dumping doorsto enhance the life and utility of the entire structure.

The invention having these general objects in view consists of the partsand combinations to be hereinafter described and then definitely pointedout in the claims.

In the drawings, Figure l is a side view of a bottom dumping bucketembodying one form of the present invention. Fig. 2 is a vie of thebucket at right angles to that of Fig. 1 looking in the direction of thearrow, Fig. 1. Fig. 3 is a view similar to Fig. 1, showing the bottomdumping doors fully opened; and Fig. I is a bottom plan looking in thedirection of the arrow, Fig. 2.

The body A of the bucket may be of any desired material, form, anddimensions, that in the drawings being shown as having two of the sidewalls converging slightly from top to bottom. Extended transversely ofthe body A, near the top thereof, is the suspending or handling bail B,the center portion of which may be provided with a loop or bent portion6 of suitable form for engagement with the usual hook or like device ofthe hoisting apparatus.

Pivotally connected to the sides of the body A, preferably upon theextended ends 0 0 of the suspending or handling bail B, are thebottom-dumping gates or doors comprising in the form of the inventionselected for illustration the side plates 0 C of somewhat triangularshape, the two plates on opposite sides of the bucket-body A beingconnected near their lower portions by the plate a, which, as well asthe lower edges a of side walls of the body, are preferably curved onthe arc of a circle having its center at the pivotal point of the gatesor doors. By this simple construction it will be noted that when thegates or doors are closed the plates 0 0 form the bottom of the bucketand sustain the weight of material within, and when they are opened moreor less these plates are withdrawn from under the material and permitthe same to flow from the bucket.

The side plates C- C of the gates or doors are extended somewhat beyondthe bottom plates 0 c, as at 0 so that when the gates or doors areclosed these extended portions form a base or extended flange by whichthe bucket may be stood upon a support, such as the ground or a flatcar,,as will be obvious. (See Figs. 1 and 2.)

In order to maintain the doors in closed position, a lock ofsuitable-type maybe provided, that selected for illustration comprisinga latch 0 pivoted to one gate or door and a keeper 0 secured to theother gate or door, suitable pins o 0 being provided to preventovermovement of the latch 0 the pin 0', when the doors are opened,sustaining the latch in such position that its inclined edge 0 will rideover the keeper 0* and enable the latch to automatically engagethekeeper, as will be clear.

Since the doors are pivotally connected to the body A of the bucket atthe same points, some oscillation of the bucket-body with respect to thedoors might take place when the bucket is standing by itssustaining-flanges 0 upon a support, and to prevent thisa limitstop I)is fixed to the body A and is adapted to be engaged by suitable recessesor slots cl 0? in the edges of side pieces 0 (1. These limit-stops servenot only to steady the bucketbody and prevent relative movement of suchbody and doors when the latter are in locked or closed position, butalso act to determine the proper closed position of each.

In a concrete-bucket subject to rough handling by inexperienced workmenit is necessary that some simple and ready means be provided for openingthe doors and dumping the contents. In the present form of the inventionthe cross-bars d cl are provided, extending between the flanges c andnear the lower edges of the side pieces C of each gate or door, andthese cross-bars serve as handrails, which may be seized by the workmenin order to draw the doors from their closed position. Owing to theweight of the material that rests upon the bottom plates of the doors itis desirable that some more efiective means for moving them be provided,and

in the present case straps cl 0Z are secured upon the side plates O ofeach door and into the loops of these straps, as shown in Figs. 1 2, asuitable hand-lever D may be inserted, thus giving any desired length ofleverage for opening the doors when the locking device or latch C isthrown back.

From the construction described it will be noted that by reason of thedoors being pivotally connected to the body of the bucket upon theextended ends of the handling or suspending bail B when the bucket islifted by means of the bail B substantially the entire body of thebucket contents resting upon the bottom plates of the doors is sustaineddirectly from the bail B, thus distributing the strains incident to theweight of the material in the most economical way and direct manner tothe suspending means. From the construction of the doors described alsoand by reason of their extensions below the bottom plates 0 a properbase is afiorded to the bucket for standing it upon a support whilefilling the bucket or transporting it from place to place, and while insuch position the limitstop D effectively prevents all relative swingingmovement between the body A and the doors of the bucket. It will benoted also that as the doors of the bucket swing about their pivotalconnection the bottom plates 0 are carried in the arc of a circle pastthelower edge of the side walls ff, Fig. 3, and such lower edge of saidside walls acts as a scraper to remove from the bottom plate 0 anymaterial that might otherwise cling thereto.

In the form of invention selected for illustration the bottom closure ordoor element of the device is shown composed of two parts pivotallyconnected to the body of the bucket or the extended ends of the handlingor suspending bail B; but it is to be understood that variations in suchconstruction may be made within the spirit of the present invention,which contemplates the provision of a transversely-swinging bottomclosure which is also provided with instrumentalities whereby it mayprovide a base or pedestal upon which the entire bucket and its contentsmay be placed in upright position upon a support.

An important consideration in the present form of concrete-handlingbucket is the fact that the doors thereof may be operated so as to dumpthe whole or only a portion of the bucket contents. This characteristicis of especial value in some forms of concrete construction, where lessthan the entire bucket contents are desired at anyone spot.

Having thus described my invention," what I claim, and desire to secureby Letters Patent, is

1. A bottom-dumping concrete handling bucket comprising a body portion,a bottom closure pivotally connected to said body por tion, said bottomclosure being provided with means for sustaining the bucket upon asupport.

2. A bottom-dumping bucket comprising a body portion, a bottom closurepivotally connected to said body portion, and adapted to swingtransversely thereof to dump all or a part of the bucket contents,andflanges connected to said bottom closure for sustaining the bucketupon a support.

3. A bottom-dumping bucket comprising a body portion, doors pivotallyconnected to the body portion and provided with bottom plates, saiddoors having extensions projecting beyond the bottom plates forsustaining the bucket upon a support.

4:. Abottom-dumping bucket comprising a body portion, doors pivotallyconnected to the body portion and provided with bottom plates,

said doors having extensions projecting beyond the bottom plates forsustaining the bucket upon asupport and means for locking the doors inclosed position.

5. A bottom-dumping bucket comprising a body portion, two doorspivotally connected to the body portion at the same pivotal point andhaving bottom plates, and a base connected to said doors for sustainingthe bucket upon a support.

6. A bottom-dumping concrete-handling bucket, comprising a body portion,a bottom closure pivotally connected to said body portion, said bottomclosure being provided with means for sustaining the bucket upon asupport, and a steadying-pin secured to the body portion to preventrelative movement between the body portion and closure when the bucketis sustained upon a support.

7. A bottom-dumping bucket comprising a body portion, two doorspivotally connected to the body portion at the same pivotal point andhaving bottom plates, a steadying-pin secured to the body portion andadapted to be engaged by said doors to prevent relative movement of suchbody portion and doors when the bucket is sustained upon a support,

IIO

and a base connected to said doors for sustaining the bucket upon asupport.

8. A bottom-dumping bucket comprising a body portion, a handling orsuspending bail secured thereto and having extended ends, doors providedwith bottom plates and hung upon the extended ends of said bail, wherebywhen the bucket is suspended the weight of material therein istransmitted direct from the bottom of the bucket to the suspendingmeans.

9. A bottom-dumping bucket comprising a body portion, a handling orsuspending bail secured thereto and having extended ends, doors providedwith bottom plates and hung upon said extended ends, said doors havingabase portion projecting beyond the bottom plates to sustain the bucketon a support.
